Before asking these questions one might search the list to see if this question had been asked and answered.
An iteration of a answer on this is "from 1968- 1973 the year is the first two digits in the (sic) serial from after 1973 subtract the first two digits from 100 (ex 2011645 - 100-20=80). before 1968 there are no serial # on .22 cal firearms."
This should help you determine the year of manufacture in regard to Glenfield/Marlin model 25.
As an example: my dad bought me a Glenfield/Marlin 25 from the local JCPenney for 42usd. I do not know why I remember that but maybe it was a lot of money in those days.
My serial number is 72422xxx, I will not show the last three digits of my serial for the sake of privacy.
My serial started with a 72 for the year 1972. That is correct because he bought it for me as a gift the spring of 1972; for rabbit hunting.
Some would say the Glenfield had no swivels for a sling but mine did and some would say the trigger should have been black but mine is chrome. Just some added information.
Good luck and peace be to the journey!
